I really like the different textures in the picture with the cartridge, and there are so many meanings a person can take from it. My husband is a police officer and trains people, so I have developed something of a fondness for that sort of thing.
Also, I really like the picture with the door; I like the salmon color of the wall. It makes me want to see the door up close to study the detail.
I like the black and white with the statue. I think it's the composition I like the best. And the shadows/shading. Maybe you could mess around with the colour, and colour in parts of it.
I like the third to last flower picture. The colours are so sharp and they seem surreal, almost. It's neat how there are only three colours in it, too.
